The temperature characteristics of ceramic capacitors are those in which the capacitance changes depending on the operating temperature, and the change is expressed as a temperature coefficient or a capacitance change rate. There are two main types of ceramic capacitors, and the temperature characteristics differ depending on the type. 1.
2. Heat-generation characteristics of capacitors In order to measure the heat-generation characteristics of a capacitor, the capacitor temperature must be measured in the condition with heat dissipation from the surface due to convection and radiation and heat dissipation due to heat transfer via the jig minimized.
*2 Maximum operating temperature: By design, maximum ambient temperature including self-heating 20°C MAX that allows continuous use of capacitors. The EIA standard specifies various capacitance temperature factors ranging from 0ppm/°C to −750ppm/°C. Figure 1 below shows typical temperature characteristics.
1. Temperature-compensating-type multilayer ceramic capacitors (Class 1 in the official standards) This type uses a calcium zirconate-based dielectric material whose capacitance varies almost linearly with temperature. The slope to that temperature is called the temperature coefficient, and the value is expressed in 1/1,000,000 per 1°C (ppm/°C).
C0G and NP0 Class 1 ceramic temperature characteristics do not show significant changes in capacitance vs temperature. Generally, heat lowers Class 2 capacitors’ capacitances, however around the Curie point (approximately 120°C for BaTiO3), the capacitance increases.
Generally, heat lowers Class 2 capacitors’ capacitances, however around the Curie point (approximately 120°C for BaTiO3), the capacitance increases. This is due to an increase in the dielectric constant as the crystal structure of the ceramic changes from tetragonal to cubic.
